Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49240, here are decompositions:
- 17 + 49223 = 49240
- 29 + 49211 = 49240
- 41 + 49199 = 49240
- 47 + 49193 = 49240
- 71 + 49169 = 49240
- 83 + 49157 = 49240
- 101 + 49139 = 49240
- 131 + 49109 = 49240
Showing the first eight; more decompositions exist.
